it brings in the academic partners like the oceanographic deomark in germany. just widens the field of people who can participate. >> widens the field of people who can participate but also widens the search. one thing they're turning away from, tony abbott said it's highly unlikely that any debris is going to be found on the ocean surface. do you think it's smart at this point, david, to call off that search from the air? >> well, i think they have to pare it back, because it seems like they're grasping at straws. it seems difficult to do any serious modeling. >> shawn, any downside, you know, when you haven't really defined the haystack really that well for the underwater search, is there a concern in giving up the air search? >> well, no, i don't think. i think the air search, in my opinion, is coming to an end, just because of the time delay and the nature of the water that we have in the area. i think it's just extremely unlikely that anything really meaningful is probably going to be found at the surface. there might still be pieces out there somewhere. w
